ispconfig3.05-SP8_update-to_3.1.7p1

Dear Support;
After ispconfig3.05-SP8_update-to_3.1.7p1https://www.sofiha-isp.com.ar:8080/login/
Never login the admin user to the control panelI had updated the password with the following
mysql -u root -p
use dbispconfig;
UPDATE sys_user SET passwort = md5('admin') WHERE username = 'admin';
FLUSH PRIVILEGES;
quit;
BUT NOT WORK!, and the I have updated using PhPMyAdmin using
Filas afectadas: 1 (La consulta tardó 0.0004 seg)
consulta SQL:
UPDATE sys_user SET passwort = md5( 'admin' ) WHERE username = 'admin'
and NOT WORK! again.
No messages about wrong user or password, simply, continue waiting for the user and password entry again.
I'll appreciate your cooperation
